FAIRFIELD, Maine — A prosecutor’s proposal to dismiss a manslaughter charge against a 12-year-old girl in connection with the death of a 3-month-old nearly two years ago as part of a plea agreement is not sitting well with the infant’s mother.

The Fairfield girl, whom the Bangor Daily News is not naming because she is a juvenile, was 10 years old when charged with reckless or criminally negligent manslaughter in the death of Brooklyn Foss-Greenaway on July 8, 2012.
